[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0021] The concrete sand washing device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the concrete sand washing device of the embodiment of the present utility model includes a shell 1, a first ring plate 2, a second ring plate 3, a plurality of sand washing plates 4, a control mechanism 5, a main drive structure 6 and a movable discharge plate 7.

[0023] The first ring plate 2 and the second ring plate 3 are respectively arranged on two sides of the housing 1 .

[0024] It should be noted that the first ring plate 2 and the second ring plate 3 serve as the main body of the grinding wheel and are used to install the subsequent sand washing plate 4 to ensure integrity.

[0025] Among them, multiple sand washing plates 4 are respectively arranged between the first ring plate 2 and the second ring plate 3, and the sand washing plates 4 are provided with blocking plates 41 distributed vertically therewith. Axles 42 are respectively provided on both sides of the sand washing plates 4, and the two axles 42 are respectively rotatably connected to the first ring plate 2 and the second ring plate 3.

[0026] It should be noted that a baffle plate 41 is provided on the sand washing plate 4 and is distributed vertically thereon. When the sand washing plate 4 scoops up a certain amount of sand and gravel, the sand and gravel on the sand washing plate 4 may fall back into the interior of the shell 1 after being driven to rotate by the first ring plate 2 and the second ring plate 3 and cannot be sent out normally. Therefore, a baffle plate 41 is provided to block one side of the sand washing plate 4 to prevent the sand and gravel on the sand washing plate 4 from falling after the sand washing plate 4 rotates.

[0027] The shaft 42 controls the rotation of the sand washing plate 4 to realize the adjustment function of the sand washing plate 4. When the sand washing plate 4 is rotated to the lowest part, it is perpendicular to the bottom surface of the shell 1. At this time, the sand washing plate 4 can only realize the stirring function of the sand and gravel, but cannot leave the sand and gravel on it for discharge. By rotating and adjusting the shaft 42 to form a certain angle, the shoveled sand and gravel can be retained on it to ensure that the cleaned sand and gravel can be discharged to the outside of the equipment.

[0028] Since the second ring plate 3 needs to install subsequent components, its opening is larger than the first ring plate 2. Therefore, an installation block is set in the second ring plate 3. The installation block is connected to the shaft 42 to ensure the stability and rotation of the sand washing plate 4.

[0029] The control mechanism 5 is arranged on the second ring plate 3 , and includes a driving rod 51 , a plurality of connecting rods 52 , a sand washing plate adjusting structure 53 , a driving structure 54 and a limiting structure 55 .

[0030] Among them, the driving rod 51 is arranged at the center of the first ring plate 2 and the second ring plate 3, the driving rod 51 passes through the shell 1, and several connecting rods 52 are respectively arranged on the driving rod 51. The other ends of the several connecting rods 52 are respectively connected to the corresponding first ring plate 2 and the second ring plate 3. The sand washing plate adjustment structure 53 is arranged on the shaft 42, the driving structure 54 is arranged on the driving rod 51, and is connected to the sand washing plate adjustment structure 53. The limiting structure 55 is arranged on the sand washing plate adjustment structure 53.

[0031] It should be noted that the sand washing plate adjustment structure 53 is connected to the shaft 42 of the sand washing plate 4 to drive the rotation of the sand washing plate 4. The driving structure 54 is connected to the sand washing plate adjustment structure 53 to drive it. The adjustment of the sand washing plate 4 is finally achieved through the drive and transmission of the two.

[0032] The limiting structure 55 is connected to the connecting rod 52 and the sand washing plate adjusting structure 53 to limit and support the sand washing plate adjusting structure 53 and ensure the stability of the entire control mechanism 5 .

[0033] It can be understood that the driving rod 51 is connected to the first ring plate 2 and the second ring plate 3 through a number of connecting rods 52. By controlling the rotation of the driving rod 51, the first ring plate 2 and the second ring plate 3 can be driven to rotate, and then the sand washing plate 4 can be driven to rotate, thereby completing the cleaning and discharge functions of sand and gravel.

[0034] The main driving structure 6 is provided on the housing 1 and is connected to the driving rod 51 .

[0035] It should be noted that the main drive structure 6 can be composed of a motor and a transmission belt. The transmission belt is sleeved on the output end of the motor and the drive rod 51. By driving the transmission belt through the motor, the drive rod 51 can be driven to rotate, thereby realizing the rotation of the first ring plate 2, the second ring plate 3 and the sand washing plate 4.

[0036] The movable discharge plate 7 is arranged on one side of the housing 1 .

[0037] It should be noted that the movable discharge plate 7 can be composed of an inclined plate and an electric telescopic rod. The electric telescopic rod is connected to the shell 1 and the inclined plate, and can control the movement of the inclined plate. The inclined plate can be kept away from the sand washing plate 4 when the device is stirring and cleaning to avoid obstruction to it. When discharging sand and gravel, it can be close to the sand washing plate 4 to facilitate receiving the sand and gravel discharged from the sand washing plate 4.

[0038] Specifically, the relevant staff puts the sand and gravel to be cleaned into the shell 1, continuously adds water into the shell 1, runs the main drive structure 6 to drive the driving rod 51 to rotate, and the driving rod 51 drives the first ring plate 2 and the second ring plate 3 to rotate through the transmission of the connecting rod 52, and then drives the sand washing plate 4 to stir the sand and gravel, so that the water can be evenly flushed on the surface of the sand and gravel, and the dust and impurities are washed out. Continuously add water to allow the dust and impurities to overflow and clean up the dust and impurities.

[0039] After the sand washing is completed, the shaft 42 is driven by operating the sand washing plate adjustment structure 53, the driving structure 54 and the limiting structure 55. The shaft 42 drives the sand washing plate 4 to rotate a certain angle, changing the inclination of the sand washing plate 4. As the sand washing plate 4 continues to rotate, a certain amount of sand and gravel can be shoveled up. The sand and gravel rotate with the sand washing plate 4 and are blocked by the blocking plate 41 and will not fall back into the shell 1. After rotating to a certain angle, the blocking plate 41 can no longer block it, and the sand and gravel slide down along the blocking plate 41 and fall onto the movable discharge plate 7, and are discharged under the guidance of the movable discharge plate 7, completing the entire sand washing process.

[0040] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the sand washing plate adjustment structure 53 includes an internal and external tooth gear 531 and two side gears 532 .

[0041] Among them, the internal and external gear 531 is sleeved on the driving rod 51 and located in the second ring plate 3, and the two side gears 532 are respectively arranged on both sides of the internal and external gear 531 and sleeved on the shaft 42. The internal and external gear 531 is meshed and connected with the side gears 532.

[0042] It should be noted that the inner and outer gears 531 are annular structures with tooth structures both inside and outside. The two side gears 532 are sleeved on the shaft 42. When the inner and outer gears 531 rotate, the side gears 532 can be driven to drive the shaft 42 to rotate, thereby driving the sand washing plate 4 to rotate and adjust the angle.

[0043] In order to clearly illustrate the above embodiment, in one embodiment of the present application, Figure 3 and Figure 4 As shown, the driving structure 54 includes a gear 541 and a first driver 542 .

[0044] The gear 541 is disposed in the internal and external gear 531 and is meshed with the internal and external gear 531 . The first driver 542 is disposed at one end of the gear 541 and is connected to the driving rod 51 .

[0045] It is understandable that the first driver 542 is a servo motor connected to the gear 541 to directly drive the gear 541 to rotate. The gear 541 engages with the internal tooth structure of the internal and external gear 531 to drive the internal and external gear 531 to rotate.

[0046] In order to clearly illustrate the above embodiment, in one embodiment of the present application, Figure 2 and Figure 4 As shown, the limiting structure 55 includes a plurality of limiting blocks 551 and limiting ring grooves 552 .

[0047] Among them, a plurality of limit blocks 551 are respectively arranged on the corresponding connecting rods 52 , a limit ring groove 552 is opened on the internal and external gear 531 , and one end of the limit block 551 is located in the limit ring groove 552 .

[0048] It can be understood that the limit block 551 is set on the connecting rod 52 and is connected to the limit ring groove 552 on the internal and external gears 531, which plays a supporting and stabilizing role for the internal and external gears 531. At the same time, the limit ring groove 552 is a ring structure, which can ensure the rotation of the internal and external gears 531.

[0049] Specifically, when the relevant staff needs to adjust the angle of the sand washing plate 4, they drive the first driver 542 to drive the gear 541 to rotate, the gear 541 drives the inner and outer gears 531 to rotate, the inner and outer gears 531 drive the side gear 532 to rotate, and then drive the shaft 42 to drive the sand washing plate 4 to adjust, completing the adjustment of the sand washing plate 4. At the same time, the limit block 551 and the limit ring groove 552 can ensure the support of the inner and outer gears 531.

[0050] In summary, the concrete sand washing device of the embodiment of the present invention can adjust the sand washing plate according to the usage situation, discharge the sand and gravel after they are completely cleaned, and improve the cleaning effect and efficiency of the sand and gravel.
